OK, quick update on installing Caponord rear wheel on Vstrom.
It fits. If I align sprocket into precisely same position related to swingarm as original Vstrom wheel rim of Capo wheel will be offset from ideal centreline to the right by 1 mm. This can be fixed by machining 1 mm off internal spacer between sprocket carrier and wheel. Takes about 5 mins on my old lathe. Still, I decided not to do it for simple reason - looking at possible play in whole assembly (swingarm, chain tensioners etc) - this makes no sense to waste time for that 1 mm on rear wheel, if it would be front wheel - I would mind, on rear - I would not.
Referrences: distance from sprocket face to centreline of rim on Vstrom: 109 mm, Capo - 110 mm. Distance from swingarm to sproket face with stock wheel 30 mm (measured from rear end of swingarm beam. To keep same distance (align sproket) with Capo wheel you need spacer 22 mm long (20 mm internal diameter).
On right side not all so rosy. Brake disk need to be moved out by 8 mm. No big deal really - Capo have 6 m8 bolts to mount disk, that's like more than enought to use spacers under each bolt or machine proper distance ring. My lathe is too small for that, so we decided to use 6 separate aluminium spacers, machined to precision of 0.02 mm (best I can do really). Still in progress. Spacer on axle on right side need to be 11 mm.
Please note - all this for Vstrom 650 and I do estimate measurements can be 1 mm off. Perhaps spacer may be 23 on left side and still 11 on right or just 12 on right. I used averages of 5 measurements and took into account that swingarm narrowing when you tightening axle nut up.
Original Capo rear disk too big - 272 mm, won't fit stock Vstrom caliper. Solution: front brake disk for Gilera RC600. Same position of holes - 158 mm, 6 bolts, central opening 140 mm, external diameter 260 mm, just like Vstrom 650 stock. Ordered.
All in all this works out really cool. Specially since Capo rear wheel is tubeless spoked type.
Now I just waiting for Gilera brake disk to arrive.
If you have big enough lathe you can machine stock Capo disk to 262 mm taking 5 mm per side - this will work.
Otherwise - get disk cut out for you.
As soon as my friend ( Vstrom owner) will upload photos - I will post them.
